Bump. :wink:

 

There is something about the inline 6 cylinder engine that just feels right in the S-30 Z cars. The sound, feel, give and overall character of the inline 6 just fits so nice. The original L6 is a sweetheart power plant, simple durable and reliable. The more modern twin cam RB’s and JZ typically harder with comparable mods, yet keep the that inline 6 character and feel of the original Z. I am surprised we don’t see more German inline 6 powered Z cars?! MAG58 beats the Merc 6 drum, it is proven performer and plentiful, the BMW engines are also just as capable, and as or more plentiful and just as capable in N/A or boosted trim as the Japanese twin cam inline 6’s. One aspect that in my mind makes them more attractive than say the RB and JZ as a possible swap option is these German engines were not only used in production cars offered here in the states, but they there are LOTS of them! That means maintenance parts are easy to get being available over the parts counter locally, and there is lots aftermarket support as well for the guys wanting go further N/A or boosted.

 

This well known 1000+HP BMW inline 6 is one example;

8.83 seconds @ 157.6 MPH!

Another perk is weight. While I can't provide irrefutable data, it's sure looking like the M50/S52 and it's cousins are lighter than the Japanese equivalents.

 

P.S. I'm digging the new avatar :2thumbs:

I'm also a big fan of BMW's. I build myself an '84 E28 5 series with a S38B38 from an E34. Put a dogleg close ratio gearbox behind it and a LSD in the rear. The Koni/Apex suspension and Brembo BIG brakes do the rest.

Last year I put a carbon airbox on it and a stainless exhaust and it sounds so aggresive now! Totally love that beast!

 

We also have a E39 M5 wich we use for drift events and the 400hp V8 is a great engine but not as snappy, angry, and willing to make rpm's as the inline S38.

 

The V8 Mpower CAN go in higher rpm levels but when you don't, he's allright with that too. The S38 DOES want to make rpm's!!

Coming from a BMW background I'd like to add that the BMW OBD I M50 motors pretty much have a standalone DME/harness. EVERYTHING and I mean EVERYTHING except for the VSS is within the engine harness. It would make for a really great swap because there is hardly any nonsense in the M50/S50 harnesses.

 

You can use these harnesses with the S50 and M52 motors along with the OBDI intake manifold. The only issue you will come to is that the OBDII cars only have one port in the head for a temp sensor. You can use your pigtail from the OBD II harness and solder/crimp them together using some research that Braap has done on the topic.

 

The BMW V8s are also a great choice but the aftermarket is VERY expensive... as it is for the inliners.

At least an aftermarket exists for BMW!

 

 

Ahahahahah...hahaha...hahah...ha...ehhhhhhhhhhhhhh

And now I'm depressed.

I mean, that doesn't sound too bad to me at the moment. I've completely removed the CIS and am starting work on a standalone before I even get the chance to start the motor! And parts may be pricey but 1500 for a pair of cams doesn't seem too horrible to me at the moment. The only two games for me in town are dbilas and MKB, both of which want more for a single bump stick than crower wants to weld, hardface, and re-grind to any specs for both cams.

 

 

I dunno, I'm envious of the aftermarket following that BMW has.

It's funny that we have completely different views of the BMW motor... I feel like it's restrictive in terms of aftermarket, and you feel it's Heaven. I can go to any speed shop and buy parts for the GenIII motor and get it tuned anywhere.

 

I swapped in an GenIII motor and COULD have it running for the price of a good condition S50 pull out with transmission. ($3000 or more)I'm being way more picky and overthinking the project so obviously that figure is bunk.

 

Alas.... This is a BMW Love thread... not hate thread.

 

The S50/S52 is a very stout motor in stock form. When it gets "tuned" or built they tend to have issues.

 

I LOVE stock BMW motors.

Bawb,

 

If I remember correctly, you're planning to boost your motor. Do you have much need for aftermaket? Your stock cams will probably be more than adequate, as you've mentioned a standalone should be in the recipe, JE Pistons can handle any CR goal, the chances of any BMW turbo manifold fitting a Z are pretty well nill, so it's a wash either way, plumbing will always have to be custom for these types of projects, etc, etc. Unless your target is 1000hp, the road blocks should be manageable. In other words, stop making excuses and get that damn thing running so we can rendezvous at the first annual EuroZfest :mrgreen:

Stock cams are suited more to boost until you star going over 600hp. Yes there are aftermarket boost cams but they are not needed for a safe motor.

 

Which Manifolds have you tried? Have you tried the bottom mount manifolds that tuck the turbo under the leaning tower of power? Rather then a top mount.

One way that BMW owners have gotten around the turbo packaging is this:

TRM also does tuning. the Stock DME is plenty powerful to run a turbo motor. a friend is running a 600 hp turbo motor with a TRM tune. Runs well when it stays together (due to stupidity of the owner not the tuner or builder).

 

Talk with the guys are TRM you'll be glad you did.

Ron: Motor's done. Car got hit by a sorority **** and is in the hands of the insurance. It's out of my hands, and I'm a little scared.

It's going to be stock for now, but at under 380 lift and barely 224 duration on the cams, is it too much to ask for something so... docile? The motor is completely out of wheeze even at 231hp and 6k.

 

Pzary: My motor was made by the swabians, not the gents from munich, hence my envy of BMW's support. <_<

We have a complete E90 donor with a N52B30 Engine and AWD transmission. We are thinking of just running a different 5 or 6 speed trans but not sure if the older Transmission will fit the E90 Engine. we plan to get all the electronics out of the Vehicle to run the engine.. but not sure if converting to Manual trans will effect the factory Engine management system.

 

We're open to suggestions.

To my knowledge I don't think BMW has changed their bolt pattern on their bellhouses for damn near 20 years now.

 

The BMW Z4 at least used to run the M54 before it switched to the N52, however the transmission never really changed (who manufactured it might have debateably). This means your manual transmission options are pretty open.

 

If you wanted a 5 speed your best bet is to find one from a 328I or E36 M3. They are cheap, all over the place, and very smooth. You could get one out of an E36 325I, but it's not as good of a transmission.

 

6 speeds you pretty much have 2 options.

 

You can get the Getreg 217 out of a BMW E46 330I ZHP, a Z4 3.0i/is, or any of the E90's (however these are hard to find with most a-holes opting for auto's)

 

You can also get the Getreg 226 out of an E46 M3. It's your strongest bet.

 

The motor you have is making about 230 at the crank, however the same engine in an X3/5 makes about 30 more horsepower, but I don't know what the difference is.

 

It's a really light engine though, and would suit a Z perfectly as far as I can tell.

 

EDIT: Oh yeah, and if you're going to use the factor EMS for the Bimmer engine, you'll need the key from that specific car, and the ignition switch as well to deal with the ews.

 

Either that or you'll have to run a standalone ems.

I was really interested in doing this, since I love BMW engines and Ron Tyler's "M"Z is pretty sweet... but after a day I'm seeing that performance parts for these are prohibitively expensive... :(

 

Gotta be the badge tax...

 

Edit: Maybe I'm giving up too soon though. My goal would be under 500hp, so maybe I wouldn't need that much engine "bling" anyway...

Oddman, The Motorsport motor is nice in NA trim, but not necessarily the holly grail in boosted form. Many FI enthusiasts prefer the non-M motors (M50, M52, etc.) and these are much more affordable. They share the same footprint (so, we know they fit) and a reliable 500HP is almost child's play.

Thanks Ron.

 

I do like the S52 you swapped in, but I was considering one of the M50's myself since it looks like they can be purchased for considerably less... and by a large margin to the RB series motors I had been considering before. Though I suppose the initial cost savings of purchasing the motor itself would be offset by the items needed to install it and build it for boost.

 

Do you know off the top of your head if the motors all share the same profile and engine mount locations?
